I havent traveled in and out of DTW for a few years and now I have several trips coming up. Where is the cheapest/fastest placed to park for Northwest these days. This have a good thread somewhere but I havent found it yet.

I have done airlines parking a number of times in the past and came to prefer Thrifys valet parking whcih they have appaenrtly discontinued.

Anybody have some good parking tips?

Thanks
